It's actually pretty interesting that at ~55 weeks, RCB, DCB and DgCB are in very close proximity to one another, then, suddenly, the non-carbonated beverages (DgCB, water) take a huge drop over the next month, with a bit of a stutter on the DCB and a continuous rise on the CB. I wonder if the significance they see in this study is due to an exogenous reaction with the extra CO2 (eg, an environmental factor).
